Answer:
6.1 seconds
Step-by-step explanation:
<u><em>The correct question is</em></u>
A helicopter flying at an altitude of 600 ft dropped a package to a lifeboat. Use the formula t= √h/4 to find how many seconds it takes for the package to reach the lifeboat. Round your answer to the nearest tenth of a second
we have

substitute the value of h in the formula


Total ratio=9+11=20
number of girls=11/20*400
=220
The maximum revenue is $700 which is at 16 combo A and 12 combo B.
<h3>
Inequality</h3>
An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let x represent the number of combo A and y represent the number of combo B, hence:
10x + 20y ≤ 400 (1)
Also:
x + y ≤ 28 (2)
The solution is at (16,12). Hence:
Revenue = 21.25 * 16 + 30 * 12 = $700
The maximum revenue is $700 which is at 16 combo A and 12 combo B.
